Vibrational sum frequency generation (VSFG), Fourier transform infrared (FTIR) absorbance, and Raman scattering were used to investigate the water structure at the gypsum (CaSO4·2H2O)–air and gypsum–water interfaces under ambient thermal and atmospheric conditions. Results show that water structural...
